| Abstract: | The measurement is based on monitoring dissolved oxgyen consumed by the two sequential reactions catalyzed by the enzymes immobilized in photo-cross-linkable poly (vinyl alcohol) resin (PVA-SbQ). A linear correlation was observed between current decrease and 0.3–2.6 mM oleic or palmitic acid. The sensor was stable in use for three days and could be used to monitor the freshness of oily food. |
